Although the number of careers calling for training and knowledge of STEM topics continue to grow, the presence of STEM education in K-12 is lacking. Therefore, there is a need to broaden the presence of STEM in current curricula. There is also a need for tools and guidelines to help educators in teaching STEM courses. Such tools should engage stud...

First-person view (FPV) drones provide an immersive flight experience for pilots. In FPV flying, the pilot wears a pair of goggles that display the video feed from the drone in real-time. This allows them to fly the drone as if they were sitting on top of it, thus creating an immersive experience similar to virtual reality and giving the sensation...

Software is a critical component of brain–computer interfaces (BCIs). While BCI hardware enables the retrieval of brain signals, BCI software is required to analyze these signals, produce output, and provide feedback. Users from multiple research areas have adopted BCI software platforms to investigate various concepts. Recently, interest in web-ba...

Drones have expanded from military operations to performing a broad range of civilian applications. As drone usage increases, humans will interact with such systems more often, therefore, it is important to achieve a natural human-drone interaction. Although some knowledge can be derived from the field of human-robot interaction, drones can fly in...

During college, students make important decisions that will affect the rest of their life while also dealing with the burdens of social and academic expectations, often while living alone for the first time. For these reasons, stress deteriorates mental health and ability to relax. Meditation has been shown to reduce stress and mitigate its negativ...

In 1997 Rosalind Picard introduced fundamental concepts of affect recognition [1]. Since this time, multimodal interfaces such as Brain-computer interfaces (BCIs), RGB and depth cameras, physiological wearables, multimodal facial data and physiological data have been used to study human emotion. Much of the work in this field focuses on a single mo...

Artists have been using BCIs for artistic expression since the 1960s. Their interest and creativity is now increasing because of the availability of affordable BCI devices and software that does not require them to invest extensive time in getting the BCI to work or tuning it to their application. Designers of artistic BCIs are often ahead of more...

HCI is a field where diversity should be considered in the systems we build and study.
